I've been having some red rashes accompanied by a greenish color on my leg for about a week, and I think it's spreading.

Have it checked: This could be a number of things and hard to know what it is without looking at it. Most commonly, this could be reaction to something (like an allergy) or infection that may need to be treated. I suggest you see your doctor soon to have it checked out properly. ...Read more

Dr, I have severe itching in leg with red rashes for last two days & reduces on Avil tab. 'm on warf 6mg & HCQ 400. Is it medicine's allergy?

Probably not: But you need to talk to your doctor about this issue. Warfarin rash tends to induce huge bruises and likely more generalized than confined to the legs. However it is possible that this may be from HCQ especially if it had been introduced within the past month or so. If problem persists, you may need to see a dermatologist. If it is helped by Advil, (ibuprofen) I would look for the presence of vasculitis. ...Read more

Red pores/rashes on leg. Spreading on another leg. Is it chicken pox?

Red pores/rashes on leg. Spreading on another leg. Is it chicken pox?

Doubt it: Cpx is a rash that generally starts around the neck and face before spreading elsewhere. The pox starts as a small bump that quickly becomes a blister about 2X the size of a BB shot, ruptures and begins to dry all in the space of 12 hrs. They come up in waves of half a dozen or more. Your description does not bear any resemblance to this. ...Read more

Hi...I was taking Augmentin for 2 days and developed a rash on my leg and on the head of my penis, the redness on my leg is going away but on my peni?

Hi...I was taking Augmentin for 2 days and developed a rash on my leg and on the head of my penis, the redness on my leg is going away but on my peni?

Reasonable to. ..: To suspect skin reaction (allergy) after taking a drug like Augmentin (amoxicillin and clavulanate) is reasonable but not confirmative. Being not anaphylactic in nature, future repetitive experience may tell. At present, just leave it alone if bearable or just apply steroid-containing skin cream lightly 1-2 times daily and watch for 3-5 days; if not resolving as wished or worsening, seek evaluation and counseling timely. ...Read more

Hi I have poison oak rashes under my kneecap and around that area. I was just wondering when you know it is starting to heal.

Hi I have poison oak rashes under my kneecap and around that area. I was just wondering when you know it is starting to heal.

You left out too muc: Where do you live? Are you sure of the cause of this? "Poison Oak" is in western US. The rash is an allergic reaction. It would be unusual for it to be confined to the area described and unusual to be the same on both sides. Eczema is common behind the knees. The duration depends on the diagnosis, 4 weeks after contact with a plant, much longer if eczema. Both respond to prescription cortisones. ...Read more

I have a red rash on the back of my leg and it itches really bad?

Leg itch: A natural question would be to ask if you came in contact with Poison Ivy or Poison Oak. In any event, if the rash is not spreading you can try Lotrisone (clotrimazole and betamethasone) creme which is over-the-counter. This should help to clear it up. If the rash is spreading you should probably see a Dermatologist. ...Read more
